Abstract

It will be evident from this and the following communications that 2,5-bis (trimethylsiloxy)furans (l ae) are useful intermediates for the synthesis of lignans, butenolides, hydroquinones and fl-quinones. As part of our program on the chemistry of enof silyl ethersI, we became interested in the preparation of 1. We faund that simply by treating succinic anhydrides 2 with triethylamine, zinc chloride and trimethylchlorosilane in acetonitrile as solvent2,
